Sorry, no etymologies found.
As Prof. Nettleship has pointed out, this seems to indicate that there are two words, _laquear_ from _laqueus_, meaning chain or network, and _lacuar_ or _lacunar_ from _lacus_, meaning sunk work.
The sunk or hollow compartments, which form the laquear of this depressed vault, differ considerably in shape and arrangement from those which were adopted when it was finally rejected.
